旱地抗条锈冬小麦新品种宁冬19号选育报告

为选育和推广“三抗一高一优”冬小麦新品种，提高宁夏冬麦产区冬小麦产量，实现冬小麦生产可持续发展。以自育品系00-301为母本、外引品种兰天26号为父本通过有性杂交，经多代系谱法选育出了冬小麦新品种宁冬19号。在2017 — 2019年宁夏南部山区旱地冬小麦区域试验中，宁冬19号2 a 8点(次)平均折合产量4 717.5 kg/hm2，较对照品种宁冬7号增产7.4%。在2019 — 2020年度宁夏南部山区旱地冬小麦多点生产试验中，宁冬19号平均折合产量5 140.5 kg/hm2，较对照品种宁冬16号增产10.2%。该品种平均株高74 cm，平均穗粒数42.7粒，平均千粒重41.7 g。籽粒容重770 g/L，粗蛋白(干基)含量132.4 g/kg，降落值314 s，湿面筋(14%水分基)含量336.0 g/kg。耐寒性强，抗旱能力强，高抗条锈病，抗白粉病。适宜宁夏南部山区旱地和周边相邻地区及生态条件类似冬麦区种植。

Breeding Report of New Winter Wheat Variety Ningdong 19 with Rust-resistance for Dryland

To breed and promote premium winter wheat variety for the improvement of winter wheat yield in Ningxia as well as the sustainable development of winter wheat production. The new variety of Ningdong 19 was bred by hybridization using 00-301 as female parent and Lantian 26 as male parent through multiple generations of selection. The average yield of Ningdong 19 in the regional trial carried out in mountainous dryland areas of southern Ningxia was 4 717.5 kg/ha, which was 7.4% higher compared with that of the control Ningdong 7. In the multiple site production trial carried out from 2019 to 2020 in mountainous dryland areas of southern Ningxia, the average yield of Ningdong 19 was 5 140.5 kg/ha, which was 10.2% higher compared with that of the control Ningdong 7. Data of average height, average grain number per spike, average 1000-grain weight, seed density, crude protein (dry basis), descend value and wet gluten content were 74 cm, 42.7, 41.7 g, 770 g/L, 132.4 g/kg, 314 s and 336.0 g/kg, respectively. Ningdong 19 has strong drought and cold resistance, high resistance to stripe rust, and resistance to powdery mildew, and it''s suitable for planting in drylands in southern Ningxia and adjacent areas for winter wheat production.
